A1: Improve your maths ability: Complete a random 10 x 10 grid in under 2 minutes.

A1: Improve your maths ability: Complete a random 10 x 10 grid in under 2 minutes.

On Saturday 8 June, I started the 10 x 10 grid challenge.

The challenge was to complete a grid made up of times tables from 1-10 (see below), in under two minutes.

My first attempt was timed at 2 minutes 10 seconds, so I knew that it wasn't going to be easy & that I had to complete it at least 10 seconds faster.

I decided to try it again on Monday & this time it took me 2 minutes 5 seconds. Mum printed me off another sheet, started the stopwatch & I tried it once more - 1 minute 55 seconds.

It felt good to have completed this challenge in a short time.

  1. Well done. Keep practising it regularly though, so that you don't lose your speed.
